The Effect of a Single Session of Transcutaneous Electrical Nerve Stimulation on Weight Bearing Asymmetry during Squatting in People with Knee Osteoarthritis

Objective: the aim of this study was to investigate the effect of a single session of transcutaneous electrical nerve stimulation (tens) on weight bearing asymmetry (wba) during squatting in people with knee osteoarthritis (oa).material-method: using a retrospective analysis of prospective study design, twenty five patients (6m/19f) with unilateral knee oa included in the study. prospectively recorded data were obtained retrospectively from the physiotherapy evaluation forms of patients who received a single session of 40-minute tens intervention to the affected knee. knee pain intensity was assessed with visual analog scale (vas). wba values during standing and squatting (30°, 60°, and 90° of knee flexion) were collected in 3 stages: before the tens intervention (baseline); immediately after tens intervention; and 24 hours after tens intervention.results: significant difference was found for wba values at 30°of squatting after tens intervention (p<0.05). reported pain intensity both in immediately after and 24 hours after tens interventions decreased significantly compared with baseline scores (p<0.001).conclusions: single session of tens intervention controls knee pain and people with knee oa can present squatting with improved inter-limb weight bearing distribution after tens intervention.
